Study Evaluating the Efficacy and Safety of Subcutaneous Methylnaltrexone (MOA-728) for the Treatment of Opioid-Induced-Constipation

13. Dezember 2019 aktualisiert von: Bausch Health Americas, Inc.

A Multicenter, Randomized, Double-Blind, Placebo-Controlled, And Parallel-Group Study Of Subcutaneous Methylnaltrexone (MOA-728) For The Treatment Of Opioid-Induced Constipation In Adult Subjects

The primary purpose of this study is to evaluate the safety, efficacy, and tolerability of subcutaneous (injection beneath the skin) MOA-728 versus placebo in adult Asian subjects with opioid-induced constipation associated with advanced illness (ie, a terminal illness such as incurable cancer or other end-stage disease) or chronic nonmalignant pain.

Detaillierte Beschreibung

Subjects received subcutaneous methylnaltrexone (also referred to as MOA-728 or MNTX) or placebo every other day beginning on Day 1 up to a maximum of 7 doses during the 2-week double-blind period.

Inclusion criteria for this study included subjects with advanced illness or subjects with chronic nonmalignant pain. The actual study population included only subjects with cancer-related advanced illness.

All subjects who completed the double-blind treatment phase of this study could elect to receive methylnaltrexone during a 12-week open-label extension study, provided eligibility criteria were met. Subjects who did not continue in the open-label extension study had a follow-up visit 2 weeks after their last dose of test article.

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
The Proportion of Subjects Having a Rescue-free Bowel Movement (RFBM) Within 4 Hours After the First Injection.
Zeitfenster: Up to 4 hours after the first injection
There were 2 co-primary endpoints for this study. This measurement is the first of the 2 co-primary endpoints. This endpoint measures the percentage of patients who had an RFBM within 4 hours after the first dose of test article during the double-blind period; data are expressed as percentages of patients for the MNTX and placebo groups. To qualify as rescue free, the bowel movement could not occur within 6 hours after a rectal intervention (ie, rectal suppository, enema, manual disimpaction). Note that efficacy results (primary and secondary outcomes) are presented for the double-blind period only. Therefore, no efficacy results are presented for the open-label period.
Up to 4 hours after the first injection
The Proportion of Subjects Having a Rescue-free Bowel Movement (RFBM) Within 4 Hours After Each Dose During Double-blind Period.
Zeitfenster: Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period
This measurement is the second of the 2 co-primary endpoints. This endpoint measures the percentage of patients who had an RFBM within 4 hours after each dose of test article during the double-blind period; data are expressed as percentages of patients by dose (first, second, third, fourth, etc.) for the MNTX and placebo groups. The definition of RFBM is described above (see first co-primary endpoint).
Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period

Maßnahmenbeschreibung
Zeitfenster
Percentage of Injections Resulting in RFBM Within 4 Hours After Test Article Administration.
Zeitfenster: Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period
This endpoint measures the percentage of injections resulting in RFBMs within 4 hours after test article administration during the double-blind period. The percentage of injections resulting in RFBMs is calculated for each patient and then data are expressed as the mean (± standard deviation) percentage for the MNTX and placebo groups. The definition of RFBM is described above (see first co-primary endpoint).
Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period
